FEDERICO GLENTON, JR, OF JOHNSTOWN, PENNSYLVANIA, ASSIGNOR TO THE LORAINSTEEL COMPANY, A CORPORATION OF PENNSYLVANIA.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed April 11, 1906. Serial No. 311,042.

To all whom it may concern:

Be it known that I, FEDERIOO GLENTON, Jr., of Johnstown, in the countyof Oambria, and State of Pennsylvania, have invented a new and usefulImprovement in Adjustable Guard-Rail Fasteners, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements inguardrail fasteners; and it has for its object to provide a simple,cheap, and efficient device of this character which will firmly hold theguard-rail in its proper relation with the main rail and which can beadjusted without withdrawing the guard-rail in order to adjust the chockmembers.

l/Vith these objects in view my invention consists of the novelconstruction, arrangement, and combination of parts, all substantiallyas hereinafter described, and pointed out in the appended claims,reference being had to the accompanying drawings, in which- Figure 1 isa plan view of a main rail and a guard-rail with my improved chockattached thereto. Fig. 2 is a sectional view on the line 2 2 of Fig. 1.Fig. 3 is a perspective View of the chock members shown in Figs. 1 and2. Fig. 4 is a view similar to Fig. 2, showing a two-member chock.

A is the main rail; A, the guard-rail.

B, C, and D are the chock members.

E is the locking -bolt, and c c the nuts therefor.

The chock members B, O, and D are tapered or wedge-shaped. The innerfaces of the members B and D are concaved, and the sides of the member Care convened. The contour of the conveXed sides of the member O is thesame as that of the concaved sides of the members B and D, Each of thechock members B, O, and D has a transverselyfluted orifice b, c, and (1,respectively, the radii of these flutes being slightly greater than theradius of the body of the bolt E. Therefore when the rails and the chockmembers are bolted together the chock members are held in horizontalalinement by U means of the concaved and conveXed surfaces and are heldin vertical alinement by means of the bolt engaging the flutes in theorifices b, c, and d.

In Fig. 4 the chock member is composed of the two wedge-shaped members Fand G, having the fluted orifices f and 9, respectively, the inner faceof the member fbeing concaved, and the inner face of the member G isconvexed.

When it is desired to adjust the guard-rail, the bolt E is removed andthe chock members are moved to or fro to give the proper distancebetween the rails, and the bolt is then replaced and the nuts drawnhome.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an adjustable chock, a main rail, and a guard-rail, tapered chockmembers having contiguous concaved and conveXed surfaces, andtransversely-fluted orifices, and a lock ing-bolt engaging saidorifices.

2. An adjustable chock, formed of wedge members having their contiguousfaces provided with interfitting portions, and also having elongatedorifices for a locking-bolt, iaild orifices having retaining means forthe In testimony whereof I have affixed my signature in presence of twowitnesses.
